Lavien Group

What Lavien Group does

Lavien Group is a privately held investment management firm founded in 2012 and domiciled in New York (operating address in Woodbury, NY). It pursues a concentrated-portfolio strategy targeting companies that meet three stated criteria: a demonstrated record of long-term value creation, a culture of innovation, and significant insider ownership. The firm is led by Founder and Portfolio Manager Michael Huber and Chief Operating Officer Susan Yee, both of whom simultaneously serve in senior roles at the private equity firm Quadrangle Group, indicating close operational and governance ties to that platform. There is no public roster of portfolio companies, fund vehicles, or AUM disclosure.

The firm does not disclose a technology product, platform, or named fund offering. Its external surface is limited to a corporate website (laviengroup.com) with public "About" and "Team" pages, plus LinkedIn and Twitter/X corporate accounts. The investor-facing portion of the site is gated by username and password and restricted to credentialed persons, with a user agreement that explicitly disclaims any solicitation, recommendation, or investment, accounting, tax, or legal advice. There are no mobile applications, APIs, integrations, patents, certifications, or disclosed partnerships beyond the informal affiliation with Quadrangle Group. Headcount is reported at 1-10.

Revenue economics for Lavien Group follow the standard private investment management model of management fees on assets under management and, where applicable, carried interest on fund performance. The firm does not publicly disclose fee structures, fund terms, AUM, vehicle names, or financial results. It is founder-financed with no institutional backing, no parent company, no funding rounds, and no subsidiaries disclosed. The customer base consists exclusively of qualified investors granted credentialed access to the gated site, with the precise number, identity, and concentration of those investors not publicly available.
